Abstract

Pour l'exécution de services d'un réseau radiotéléphonique mobile dépendante de l'emplacement, à l'intention d'un abonné (TNR) mobile inscrit dans le réseau, par exemple la tarification dépendante de l'emplacement ou des tâches associées à des routes/à des zones, en cas d'une modification de l'emplacement de l'abonné, le profil de service affecté à celui-ci, en ce qui concerne les services utilisés par l'abonné (TNR), dont l'exécution est déjà commencée, est actualisé en continu. L'information d'emplacement concernant l'emplacement (A, B, C) actuel d'abonnés mobiles est reçue, du côté du réseau radiotéléphonique mobile, par un système de localisation (SAT) et combinée avec un plan de services qui décrit la dépendance des services par rapport à l'emplacement, les profils de service actuels étant dérivés de cette combinaison pour les abonnés concernés. A partir du profil de service actuel de l'abonné (TNR), un message concernant l'offre de service actuelle spécifique à l'abonné peut être dérivé, envoyé à l'abonné et affiché du côté du terminal de l'abonné.
